A body floats in a liquid contained in a beaker. The whole system as shown falls freely under gravity. The upthrust on the body due to the liquid is

A

zero

B

Equal to the weight of the liquid displaced

C

Equal to the weight of the body in air

D

Equal to the weight of the immersed position of the body

Text Solution

Verified by Experts

The correct Answer is:
A

(a) Upthrust ` = V rho_(liquid) (g -a),` where, a = downward acceleration, V = volume of liquid displaced But for free fall a = g `:'` Upthrust = 0`
